Current radar loop for Houston, TX.

A cluster of thunderstorms is expected to develop across central and northeast Texas Tuesday afternoon. This cluster of storms is expected to move across southeast Texas Tuesday evening through early Wednesday morning. Some of these storms will be capable of becoming strong to severe, mainly Tuesday night.

Showers and thunderstorms expected tonight into Wednesday morning. Locally heavy rainfall expected and localized flooding is possible.

Unsettled pattern will lead to continued high chances for showers and thunderstorms, with additional rounds of moderate to heavy rainfall. This rainfall will generate runoff and river responses, especially where we see repeated heavy rainfall over the same locations.

High rain chances through the weekend. Temperatures near normal through the weekend.

There is a high risk of rip currents along all Gulf facing beaches through Tuesday evening. Stay away from rocks and swim near a life guard.
